Script Type AdoptionTRINITY EXCLUSIVE
EXCLUSIVE - Daily share of Bitcoin outputs by script type (P2WPKH / P2PKH / P2SH / P2TR), normalized to 100 %. Stacked-area view of the network's technical modernization pace, from full node script type indexing.

What is it?
Script Type Adoption measures the proportion of transactions and UTXOs using each Bitcoin script type: P2PKH (legacy), P2SH (multi-sig, complex scripts), P2WPKH/P2WSH (native SegWit), and P2TR (Taproot). Calculation counts outputs created by script type over a period, then normalises to percentage of total. This distribution reflects the technical modernisation speed of the ecosystem - wallets, exchanges, and services.
How to read
Growth of P2WPKH/P2WSH and P2TR at the expense of P2PKH indicates progressive adoption of protocol improvements. A stacked-area chart shows the evolution of relative shares. Rapid Taproot adoption reduces the on-chain footprint and improves fungibility. Migration pace marks ecosystem technical maturity.
Key zones
SegWit crossed 50 % of transactions in 2020 after three years of gradual deployment. Taproot (activated November 2021) surpassed 10 % of outputs by late 2023 and continues growing. P2PKH remains present due to unspent legacy UTXOs and some outdated wallets.
What to observe
Taproot migration speed is the most relevant indicator currently. Slope breaks (sudden adoption after a major exchange update) and plateaus (type saturation) are informative. P2SH share may temporarily increase during multi-sig activity spikes.
Historical context
Bitcoin evolved from 100 % P2PKH in 2009 to a multi-script landscape. SegWit (BIP 141) activated in August 2017 took 3+ years to reach majority. Taproot (BIP 340/341/342) activated in November 2021 follows a slower adoption curve, partly because gains are less visible to end users than SegWit.
Expert notes
⚠️ Trinity Exclusive Model - Taproot adoption is particularly important for privacy: multi-sig and complex script spends become indistinguishable from single-sig spends in P2TR outputs. This degrades heuristic chain analysis capability. For analysts, the distinction between 'created outputs' and 'spent outputs' by type is crucial - a P2PKH UTXO created in 2012 and spent in 2025 appears as P2PKH at creation but may produce P2TR change.
Common mistakes to avoid
Interpreting low Taproot adoption as a soft-fork 'failure' is incorrect. Adoption depends on wallet and exchange development cycles, not user interest. Additionally, confusing 'transactions using X' with 'UTXOs of type X' yields very different numbers - stock metrics (existing UTXOs) vs flow (outputs created) tell different stories.
